As staff member you have rights to manage group chats.
As staff member you can create a group chat within your community.
You can select the active users from a dropdown list and invite them to participate in the group chat. Give the group chat a relevant name that refers to the subject.
Via the setting wheel (top right) you can perform multiple actions as staff member for this group chat. By removing a member, the conversation is removed from the user’s conversation list in the left panel. This member does not get notifications when new messages are posted by other members. Also the member's name and avatar are removed from the group member list. Previous messages from this member remain visible in the group chat.
You can also add a new member to an existing group chat or re-activate a removed member again. Click the settings wheel and add the specific member.
Via the settings, you can also rename the chat. Click on the pencil next to the current chat name and type the new name.
